Hello! Today we'll learn about possessive pronouns. These are special words that show who something belongs to. Instead of saying 'Tom's book' or 'Lisa's book' over and over, we can use words like 'mine' and 'yours' to make our sentences shorter and clearer.
There are seven main possessive pronouns in English. Mine belongs to me, yours belongs to you, his belongs to him, and hers belongs to her. We also have its for things, ours for us as a group, and theirs for them. Each pronoun matches with a different person or group.
同学们好!今天我们来学习英语中的人称物主代词。物主代词是用来表示某个东西属于谁的特殊词汇,它们在日常英语中非常重要。让我们一起来探索这个有趣的语法知识吧!
物主代词是用来表示所有关系的词汇。它们分为两种类型:形容词性物主代词,用在名词前面,比如my book我的书;名词性物主代词,可以单独使用,比如This is mine这是我的。理解这两种类型的区别很重要。
现在让我们来看形容词性物主代词的完整表格。第一人称单数I对应my我的,第二人称you对应your你的,第三人称单数he对应his他的,she对应her她的,第一人称复数we对应our我们的,第三人称复数they对应their他们的。这些词都要放在名词前面使用。
接下来是名词性物主代词表格。第一人称单数I对应mine我的,第二人称you对应yours你的,第三人称单数he对应his他的,she对应hers她的,第一人称复数we对应ours我们的,第三人称复数they对应theirs他们的。注意his在两种情况下都是一样的,这些词可以单独使用,不需要后面跟名词。
让我们通过实际例句来练习物主代词的使用。This book is mine表示这本书是我的。Is this pen yours询问这支笔是你的吗。That bike is his表示那辆自行车是他的。The doll is hers表示这个洋娃娃是她的。The classroom is ours表示教室是我们的。These toys are theirs表示这些玩具是他们的。通过这些例子,我们可以更好地理解物主代词的用法。
It's important to understand the difference between possessive adjectives and possessive pronouns. Possessive adjectives like my, your, his, and her always come before nouns. For example, 'This is my book.' Possessive pronouns like mine, yours, his, and hers stand alone and replace the noun. For example, 'This book is mine.' Remember: adjectives describe nouns, pronouns replace nouns.
Let's practice what we've learned! In the sentence 'This is my book,' we use 'my' because it comes before the noun 'book.' In 'The book is mine,' we use 'mine' because it stands alone. Remember these key points: use possessive adjectives before nouns, and use possessive pronouns by themselves. With practice, you'll master possessive pronouns perfectly! Great job learning today!
